APPARATUS FOR `CASTING LINKS IN CHAIN FORM.

To all whom it may concern:

Be it known that I, CHARLES SHIELDs MOINTIRE, a subject of the King of Great Britain, residing at 83 Efira road, Brixton, London, England, have invented certain new and useful improvements in Apparatus for Casting Links in Chain Form, oi' which the following is a speciiication.

This invention relates to that class of apparatus wherein links of a chain are cast in a mold composed of four pieces, and in which mold a link already cast is placed in such position that the newly cast link is in engagement with same, and as the casting proceeds, a chain is formed. In such constructions hitherto known, a great disadvantage has occurred by reason of the construction of the sections forming the molds, and by the extreme heat to which the molds are subjected to, by the molten metal preventing proper tting of the sections ofthe molds together to insure a well made link without jagged edges being formed at the seams, or meeting edges of the mold sections.

In all molding devices for casting chain links, the sections formingthe mold have been placed together in a box or like appliance, and clamped or held together by pins, wedges or the like, and in consequence, the sections, after casting, have to be removed separately and laid upon a bench to cool, to be afterwards handled and refitted lor casting. This entails great labor, and a slow process of working, and as before stated, imperfect working and construction ol links by reason of the indifferent register of the sections, dueto heat and other causes.

Now the object of my invention is to overcome these disadvantages, and construct an apparatus which shall always be efficient the sections always in register with each other, thus insuring a proper shaped link at each casting, and of such a nature that the apparatus will not get so heated as to be unworkable for a time, so insuring continuous working, and further, all the parts are connected together and easily operable by hand to place them in position for casting and removing oi the link or chain.

My invention will be clearly understood from the annexed drawings in which, at Figure 1, I show a perspective elevation of my apparatus vin position for casting two links and attached to a base which forms Fig. 2. is a plan of the apparatus with the handles removed.

Fig. 3. is a face view of two half molds on the line a a, oi Fig. 2. Fig. 4. is a plan of the two bottom half molds on the line l) b of Fig. 3. In Figs. 3 and 4, the casting two links at a time and the making of one chain is shown, the position of the already made links being shown in dotted lines Fig. 3, and full lines Fig. 4.v Figs. 5 and 6, are similar views 'to Figs. 3 and 4, but showing the position of the already made links, Fig. 5, in dotted lines, and Fig. 6 in full lines, when casting links i'or making two chains vat a time. Fig. 7. is anl end elevation of the apparatus with the handles removed.

According to this invention, the apparatus is constructed with a mold composed of four pieces or sections 1, 2, 3 and 4, the section 1 being attached to a base 5 forming part of a stand or bench, and having a projecting member 6, which forms the rest or support for the section 2 when the bottom half mold is closed up.

' Each bottom half mold is formed with up* rightly extending arms 7, 8 and 9, and such arms have grooves 10 which extend into the mold as shown, and when the two half molds 1, 2, are placed together, the grooves 10 form two holes of the shape of a portion of the links to be cast. The arms 8 have two grooves 1() which extend outwards through the sections 1, 2, to the arms 7, 9, so as to form holes for two links.

. Each halfl section 3 and 4 is formed with grooves 10 which coincide with the grooves in the sections 1 and 2, and when the whole of the sections are joined together, the combined grooves form two holes of the shape of the link, and into which the metal is poured to form the links.

Each groove in the upper sections 3 and 4 has a passage 11 at the upper part leading to a recessed portion, and when the whole of the sections are placed together, these recessed portions form a receiver 12 into which the molten metal is poured for casting the links. To each section 1, 2, 3, and 4, is attached a rod 13, 14, 15, 16, such rods being connected together at a distance from the mold by a hinge joint 17. The rods 14, 15, 16, are continued on the side of the mold opposite to that of the hinge, and terminate in handles 18, by which the mold sections are opened n tion acts as a block or wall which when the sections 3 and 4 are closed on to the sections 1 and 2, insure that the sections 3 and 4 are in register with 1 and 2, but a depending lip from the sections 3 and 4 will answer the saine purpose.

' The meeting faces and edges of the sections 1, 2, 3 and 4 are smooth, and lit to a nicety, and in assembling the sections together, the section 2 rests on the projecting member 6, and the sections 3 and 4' upon the sections 1 and 2, with the depending portion or portions of the rods 14, 15, close up to the outer edge of the sections 1 and 2, the whole being in register and held thereat. If I desire to cast links separate, I now pour the molten nietal into the receiver 12, the metal flowing into the holes 10 and forming the links, and after suflicient cooling, the sections are opened out, when the newly made links fall away on to the bench or table 5 to be afterwards removed, and on a reassembling of the sections, a further casting can be effected.

When I desire to cast links so as to form a single chain, I close the sections 1 and 2, and I place already made links 19 over the arms 7, 8, and the end link 19 of a chain over the arm 9 as shown in Fig. 4. I then close the vtwo sections 3 and 4, together, on to the sections 1 and 2, pour in the molten metal, when the separate links and the end linkof the chain will be connected. This being one casting I connect up three links and add at one operation four links to a chain.

When I desire to build up two chains at one time, instead of placing a previously made link over the arm 8, I place the link at one end of each chain, and an already made link over each arm 7 and 9, and then proceed to cast, thus having each length of chain built up two links at a time.

As before stated, the hinge 17 is at a distance from the mold, this is to prevent the heat from the molds interfering with the proper action of the hinge and allowing of proper positioning of the mold sections to insure perfect re ister, and the arms 7, 8 and 9 allow of t e previously made links being placed in position, and open to the air, so that they do not get highly heated, as is the case when within the mold.

By this invention, each link is cast practically smooth on the outside, without any sharp projecting edge caused by the meeting surfaces of the sections, and the only part to be removed after casting is a small portion which generally fills the passages 11.

That I do claim and desire to secure by Letters Patent is An apparatus for casting chain links comprising a mold formed of a pair of lower and a pair of upper sections, each of said lower sections provided with three upright arms arranged in longitudinal alinement, the intermediate arm being formed with a pair of grooveswhich extend in the body bof each lower section, said outer arms each provided with a groove terminating in a groove of an intermediate arm, each of said upper sections provided with grooves having the lower terminus adapted to register with the upper terminus of the grooves of a lower section, the grooves of the lower sections adapted to oppose each other and the grooves of the upper sections adapted to oppose each other so that when the grooves in the upper sections register with the grooves of the lower sections a pair of continuous channels are formed, said upper sections provided with means constituting av receiver' and which communicates with the grooves in said upper sections, and means for moving the sections together and for insuring the registering of said grooves, combined with a suitable support for the mold.

In testimony whereof1 I have hereunto set my hand in presence of two subscribing witnesses.
